SAFETY-RAZOR. Y

T0 all whom t may concern.'

Be it known that I, HoorER CoYNE, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented ycertainnew `and useful Improvements in SafetyfRazors; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My present invention relates to improve-V lments in safety razors, andit is intended to provide a cheap, simple, eiicient and durable form ofsafety razor in which the razor blade is held rmly in place when in use,and in which the parts may be readily assembled and disassembled whenvit is desired to clean the razor or substitute another bla-de, or forother purposes.

It is well known that with the safety razors now generally in use, thereis more or less trouble and annoyance in taking the razor apart andcleaning up the same and then restoring the same to the originallassembled position each timethat the razor is used.

My present invention relates especially to improvements on the deviceshown in my Patent No. 1,142,810, granted June 8, 1915, and entitledImprovements in safety razors.

The object of my invention is to reduce and simplify the number of theseparts, and to facilitate the operation of assembling and disasseinblingthese parts, which will be more fully hereinafter described.

Reference is had to the accompanying drawings in which Figure 1 is a topplan view of the complete razor ready for use; Fig. 2 shows the supportfor the razor blade, with the blade and its sliding locking piecedetached; Fig. 3 is a side elevation of the razor with the partsassembled; Fig. 4 shows a section along the direction of the arrows,parts being shown in elevation; Fig. 5 is an end view as seen from theright, of Fig. 1, the parts being shown on a larger scale; Fig. 6 showsa section along the line 6-6 of Fig. 4, and looking in the direction ofthe arrows, the parts being shown on a larger scale; Fig. 7

shows a similar section along the line 7 7 I Vin the position shown inFig. 2, the razor of Fig. 4, and looking in the direction of the arrows;Fig. 8 is a detail showing one side of the reversible razor blade; andFig. 9 is the line 4-4 of Fig. 1, and looking in Specification ofLetters Patent.

a detail Showing the Sliding locking piece" for locking the'razor bladein place on its support. Figs. S and 9 are on the same scale as thecorresponding parts shown inv Figs. .1 to 4.

A represents the holder or support for the razor, whose head A isVpreferably provided with clearanceslots a beneath the edges of the blade. 'The head of the blade support is provided with a rectangular luga stamped' out of one side thereof opposite the vcorresponding recess a0which lug is adapted to engage the central slot b of the reversiblerazor blade-B, and to steady the razor blade against movement laterallyvor longitudinally when the blade is clamped in place,

as will be hereinafter described.'

Q and C represent the two lend studs which are provided with heads c,having engaging flanges asshown in Figs. 5 7,

which heads pass freely through the holes b in the razor blade, andpermit the blade to be readily slipped vin place or removed whendesired.

D represents the locking piece which is made of a single piece of metal,shown in i the bladeY firmly in place on the combined guard and support.The blade is, moreover, positively lockedV against lateral orlongitudinal movementrelative to the support A, due to the engagement ofthe rectangular lug a and the slot b in the center of the razor blade.

E represents the handle which is hinged to the part A in the usual way.This handle is preferably of such construction as to permit the supportA to be swung freely therethrough, thus facilitating the use of theimplement on either side of the yface of the y user. i

To assemble theparts, the holder A being blade is put in place, engagingthe boss a and slipping over the studs C and C; and

then the sliding locking piece is slid longitudinally from the end ofthe support to engage the flanges on the studs B and B. To disassemblethe parts, simply slide the locking piece in the opposite direction,until it is disengaged from the two studs C and C, and then remove therazor blade,

By having the slot Z) in the center of the razor blade, and the lug cein the center of the head A of the razor support, the razor blade may beapplied upside down, `thus reversing the cutting edges, when desired.

It will be seen that the device is of such constructcn that it may bereadily cleaned when desired, and that the razor blade may be quicklyapplied or removed; thus the de- Y vice consists essentially of threeparts-the support carrying the centering and holding` lug and thelocking studs, the razor blade, and the sliding locking piece forholding the blade in position. The locking piece should be made ofresilient material so that it will automatically press down on therazorblade and stiffen same near its edges.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States is In a safety razor, thecombination with a holder having its head adapted to form a support forthe razor blade, said head being provided with a central rectangular lugstamped out of the center thereof, with studs having flanged headsprojecting from the same side or' said support as said lugs, and spacedapart therefrom and parallel therewith, of a blade perforated to slipover said studs and to engage said lug, thus preventing lateral orlongitudinal movement, and a sliding resilient Alocking piece,archshaped in cross section and having the edges turned inward andslightly upward toward the arch, said member being adapted to engage theiianged heads of said studs and to press down the razor blade and lockit in position, substantially as described.

ln testimony whereof I athx my signature.
